ShadowAlice is a live wallpaper that combines Halloween and Alice in Wonderland themes. The wallpaper features a falling girl looking at a dream, with a door leading to a sweet fragrance. The free version of the app has limited functionality and is maintained for only 5 days after setting it up.

The app offers 9 color themes, object display options, and effects such as blur and emboss. The app's Halloween and Alice collaboration is perfect for those who love the spooky theme and the whimsical world of Alice in Wonderland. However, the limited functionality of the free version might not satisfy some users who want more features.
